Summary

In some cases:

• customers may only be interested in knowing the current status of their requests together with updated comments from support team
  OR
• support team prefers the status change log to be hidden as a lot of status changes might be involved without comments

the reason is the status change log may become unnecessarily lengthy after some time, distracting customers from the really important content

this is currently not configurable in JIRA Service Desk, and the status change log is always visible in the customer portal

Suggestion

Add the ability to show/hide status change log in customer portal, in a way that the current status is always available (next to the title/summary of the request) but the status change log can be shown/hidden:
